Long ago shortly after I bought my first house in the early 1980s, I was cleaning up the back yard. Mowing, and removing dead bushes. I needed more gasoline, so I went to the gas station and realized I was hungry and decided to get a burger at the fast food place next door.
I was wearing an old worn out pair of jeans, both knees had holes, and they were my yard work and work on the car jeans. Some guy with a very thick accent came over to me and asked where I bought my jeans. They were old, and I truly had no idea where I had bought them, and I was puzzled why he cared where I got them. They were old 501 jeans available everywhere.
I hated 501 button fly jeans, but in the 1970s every single pair of jeans with a zipper had the stupid bell bottoms or even worse elephant legs. Only the 501s were the same old jeans. I was really happy when bell bottoms went away, and the 501s became yard work clothes. Screw the stylists and fashion designers, I hated the 1970s styles, well except for the mini-skirts the women wore!
Anyone that has really needed to use the bathroom has done the "I hate button fly jeans" dance.
Anyway, I told the guy I bought them new and in perfect shape, and I wore them out in honest hard work. I have walked through the mall (shudder) and glanced at the jeans for sale. All of them are beat up, and they even sold some with blobs of paint on them to look like a sloppy painter wore them. I do not understand buying new jeans that are pre-worn out. Just insane. Get off my lawn!
